Question

In the following figure find the value of d.If c=57 degree a=c/3 find the value of d​

Answer 1

Step-by-step explanation:

C = angle a + angle b ( reason: they are alternat interior angles)

57 degree = a+ b

a = d ( alternat interior angles)

a = C/3 given

b+ d = 180 degree ( co - interior angles )

C/3 + b = 180 degree ( as we prove above that a= d)

a+ b = 57

b = 57 - a

b = 57 - c/3

c/3 + 57 - c/3 = 180

Answer 2

Answer:

180 is your answer..

hope it helps you ☺☺
